Somebody else mentioned this before but none of the programs we've seen 
so far seemed to need a special random number generator. So, the default 
one, which is already randomized, would suffice. Just drop the line above.

When there is a syntactic need for a variable but that variable is not 
used, the idiomatic way of naming that variable is '_':

     howManyTimes.iota.map!(_ => dice(0.6, 1.4))

(Note: I did not write rnd.dice.)
